Genetically modified organisms (GMO) are plants, animals, bacteria or viruses that have been altered through the transfer or deletion of genes into or from the organism under consideration.
The genetic modification of animals to obtain transgenic animals started in 1980. The first transgenic animals were mice, which are still the most frequently used transgenic species.
In this video and animation produced by Sonal Katyal MSc, Roslin PhD student Gus McFarlane explains how genetic modification, through a process called transgenesis, works and its potential to improve animals’ welfare, productivity or even produce a crucial drug to save human lives.
